In a move towards speed and reliability Propel (an object persistence layer) in it’s new 1.3.0 version drops its integration of Creole (database abstraction layer) in lue of PHPs new PDO (PHP Data Objects) extension. This fundamental move establishes leverage for Propel to take further control of PHP 5s new OOP features for its database connections. With this change there will be a number of changes required of those upgrading, particularly for those who are executing SQL directly. PDO’s API is loosely similar to Creole’s, so this change shouldn’t require any major re-architecture. A few of the changes include a new PHP minimum requirement of PHP 5.2.x, several method signature changes, mysqli adapter was removal, SPL autoload integration, and API changes for extending classes.
